Manufacturers Note: The E3 printed on the light bezel means it's Light Engine E3 circuit, the input voltage is 2.2V-4.2V, so please be cautious when you use this bezel on other bodies, you should NOT use 2 CR123 batteries, or the light bezel will be damaged due to excessive voltage input.

Battery Tube & Tailcap: Threads on battery tube of NiteCore Extreme are anodized. Threads are lubricated nicely. There is a translucent O-Ring sitting behind the threads. The advantage of anodized threads is it prevents the thread wear during normal usage. This is due to the fact that anodizing provides hard surface of aluminium oxide which is resistant to wear.

Detailed review here...


Update 1: Added Lots of Pictures and Some additional information here...

Beamshots will post by evening.... waiting to get dark :D ... Very good beam and tint is my initial impression....

It appears that nitecore site is not yet updated, if you are interested in this light, please visit CPFMP Sales & Informaiton Thread from EDGETAC: 177497

Update 2: OK now we have some of the things setup...and completed...

First let's talk about the total output as many have wondered the difference between the two. NDI Silver and NDI Extreme. The NDI Extreme indeed has more output with same chemistry battery Li-Ion.

The output is different. Here is the chart. <edit> chart removed, see update 4
Beamshots are done, Resizing and posting soon ;) in a few moments....

Update 2: Beamshots 1
NiteCore-DI-Extreme-BeamMatrix-CPF.jpg

More beamshots Here...

Update 3: Beamshots 2 Here is the comparison between beamshots of NiteCore Extreme and NiteCore Defender Infinity Silver
NiteCore-DI-Extreme_vs_NDIS-BeamMat.jpg


More here...

Update 4: Comparitive Output Here is the comparison chart for outputs of NiteCore Extreme and NiteCore Defender Infinity Silver with various battery types and conditions
NiteCoreInfinityLightOutputs.gif


From the above chart it is clear that there is a distinct difference between outputs of NiteCore Extreme and NiteCore Defender Infinity Silver. Please be aware that the sample size is ONE and there is always a variance in battery, electronics and LED. Some times LED may be one off the premium. Some tmes batteries may be underperforming. In short, there are a lot of factors that affect the total light output. The fact remains that light output of NiteCore Extreme is higher than NiteCore Defender Infinity Silver for similar battery chemistries. selfbuilt in his initial views has also confirmed the fact. I will update this section as soon as his review is posted.

Update 5: Extreme Close Up Pictures Here are a couple of extreme closeup pictures for NiteCore Extreme
NiteCore-Extreme_ExtremeCloseUP_09.jpg


NiteCore-Extreme_ExtremeCloseUP_07.jpg

More here...

Update 6: Runtime Test: The runtime for NiteCore Extreme with AW RCR123 on MAX light output is about 47 Minutes till 50% . NiteCore Extreme runs completely in regulation. Runtime for NiteCore Extreme for lesser output levels will be considerably more. From the runtime, it is evident that NiteCore Extreme has one of the efficient circuits out there. It is as of till date the best combinaiton for longest running and highest brightness.

These results are in line and similar to selfbuilt's results prooving consistancy in light runtime for different samples. More excellent runtime tests by self built can be viewed on selfbuilt's excellent review thread

Same here. But then I realized my Raidfire Spear has been welded to my left hand for several months, and I figured if the Extreme was anything like that one I had better go for it. The "new toy" infatuation usually wears off after a week or so, but that hasn't been the case with my Spear.

Re: CPFReviews.com: NiteCore Defender Extreme TM ... Initial Preview

quick question...what are the main differences between the Extreme and the Infinity? It seems like the Extreme is a bit larger and is slightly brighter (~10 lumens) at max output. Besides the fact that it runs on different batteries, are there any other major differences?

Looking forward to your beam shots and impression on the lumens count. Is it brighter than the Infinity? How much?

Thanks again.

:grin2: No :) .. But you can check sales thread from EDGETAC

Unfortunately that is not a sales thread. Edgetac is not selling them direct. And there is not a Nitecore dealer in the USA that I will do business with. I will keep my eye on the BST.

Re: CPFReviews.com: NiteCore Defender Extreme TM ... Initial Preview

It is brighter than Infinity because NDI is rated at 190 emitter lumens and NDE 200 torch lumens. That's why it runs 30 minutes shorter on RCR123 than NDI using 14500.
